What is the IP waterproof and dustproof rating in the lamp logo?

October 19, 2022

IP is the abbreviation of English ingress protection, which is derived from the international electrotechnical IEC standard. In order to prevent solid foreign objects, such as dust, debris, etc., from entering the interior of the lamp, and for water protection, there will be a shell to protect the lamp insulation and protect the light source. The two numbers after IP indicate the degree of protection strength. The first number indicates the degree of protection against solid objects such as dust and foreign objects. The second number indicates the protection against water, moisture, etc.

The first characteristic number: dustproof level

IP0X: no protection
IP1X: Protection against the entry of foreign objects with a diameter of 50mm and above, such as hands.
IP2X: Protection against the entry of foreign objects with a diameter of 12.5mm or larger, such as fingers and small objects such as remote controls.
IP3X: Protection against the entry of 2.5mm solid or larger solid foreign objects, such as small devices such as wires
IP4X: Protection against entry of solid foreign objects of 1.0 or greater
IP5X: Prevent excessive dust from entering and causing damage to electrical appliances

IP6X: airtight, no dust ingress at low pressure of 20 mbar

The second characteristic number: waterproof rating

0 : no protection
IPX1: Anti-drip Typical duration is 10 minutes, measurement is 10.5mm/min
IPX2: Anti-drip water at 15 degrees tilt, 4 times 2.5 minutes test, water volume is 30.5mm/min
IPX3: Anti-splashing water splashing test Usually there is a test of watering time, such as about 5-10 minutes
IPX4: Splash-proof Splash Test The enclosure can block splashes from any direction
IPX5: Anti-spray water spray test The nozzle diameter is usually 6.3mm, the distance is 2.5m-3m, the intensity reaches 12.5L/min flow, and the time is generally at least 3 minutes
IPX6: Anti-strong water jet Test conditions: Nozzle diameter 12.5mm, distance 2.5m-3m, water flow rate up to 100L/min, similar to violent waves, strong water jet impact
IPX7: Anti-immersion Water immersion test, the time is short, the test product should be immersed in the water tank, the distance from the top to the water surface is at least 0.15 meters, and the test time is usually 30 minutes
IPX8: Diving resistance A more severe waterproof test, usually more stringent than the IPX7 rating. As specified by the product agreement.
It should be noted that products that can pass the high-level waterproof test may not be able to pass the low-level waterproof test. For example, products that pass the IPX7 level waterproof test may not pass the IPX6 test, mainly because the IPX6 level waterproof test, its water spray The resulting water pressure is higher, but the force of the immersion test is more uniform.

Usually we say that the waterproof rating of the lamp refers to the waterproof rating of the whole lamp housing. Products with strict quality requirements not only have high requirements on the waterproof test of the casing, but even the internal components also need to undergo strict tests, such as the salt spray resistance test of the light source LED lamp beads, vibration test and so on. Improving the dustproof and waterproof IP level of lamps is usually related to the material of the housing, welding process, sealing, and some sealing materials, such as the characteristics of sealing rubber rings, sealing glue, and potting glue. The craftsmanship of these materials and the quality of the glue also determine whether the product can be kept dustproof and waterproof for a long time and effectively.

For lamps, general indoor lamps need to have protection against electric shock. Its dustproof and waterproof rating should not be lower than IP20, and the IP rating of lamps and lanterns with anti-electric shock protection and waterproof vapor condensation should not be lower than IP21; , lamps in various application scenarios will have different IP level requirements.
